FIELD: obtaining of unsaturated hydrocarbons. ^ SUBSTANCE: method involves obtaining a mixture, containing one or more cyclic unsaturated hydrocarbons and surplus from one or more non-cyclic unsaturated hydrocarbons, where the molar ratio of the non-cyclic unsaturated hydrocarbons to the cyclic unsaturated hydrocarbons ranges from 5:1 to 3:1. The indicated cyclic unsaturated hydrocarbons have DeltaG less than 0 at 25°C and have a ring structure, containing "x" atoms of carbon. The method also involves reaction of a cross-metathesis mixture of one or more cyclic unsaturated hydrocarbons and one or more non-cyclic unsaturated hydrocarbons. The method is characterised by that, the cross-metathesis stage is carried out under effective conditions with formation of a mainly non-cyclic unsaturated hydrocarbon product, containing one molecule of the indicated cyclic unsaturated hydrocarbon and more than "x" carbon atoms. The indicated unsaturated hydrocarbon products contain 10-16 atoms of carbon. ^ EFFECT: cheap method, with high selectivity of obtaining non-cyclic unsaturated compounds, containing from ten to sixteen carbon atoms. ^ 24 cl, 10 ex, 9 tbl, 4 dwg |
